The Moscow Mule (vodka, ginger beer, and lime) was first created in 1947 and is traditionally enjoyed in a frosty copper mug. This updated version of the classic mug is handcrafted from hygienic, easy-to-clean stainless steel with a copper plated exterior and a solid brass easy-grip handle. This mug combines old world charm with new materials to enhance your Moscow Mule experience, and is also perfect for enjoying beer, mint juleps, and other favorite cold beverages. Hand wash only. Not for microwave use.
